FLEXIBLE BEATER :AND SCRAPER.

Appncatin med ret'iiary 11.1908. i serial NQ. 415,872.

To all whom it may concern:

Be. it known that [,"'J0HN lV. KOHLHPP, a citizen of the United States, anda resi-l dent of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Flexible Beatersand Scrapers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompany* lng drawings, and to the letters of reference marked thereon, whichl form a part of this specification.

This invention relates more particularly to beaters, for that class of machines set forth in my applications for Carcass scraping and polishing machines, filed on the 29th day of March, 1907, Serial N o. 365,416, and Hogscrapers, led'on the 18th ofl May, 1906, Serial No. 317,451, in which rotative shafts each provided` with more or less flexible .beaters having Scrapers secured thereon, are used and in which the rotation of the shafts impels the Scrapers and beaters against the animal carcasses supported in operative relation thereto for the purpose set forth. Heretofore I have employed frequently for beaters, canvas belting or chains of suitable length or belting having chains secured thereon. These have been rigidly bolted on the shaft that the same may act to l some extent centrifugally to strike or beat the hair from the carcasses. In either construction, however, the beaters yield too readily from contact with the carcasses and as a resultif the carcasses are rough or in other words, are of tough or old hogs killed late in the season, sometimes the hair and bristles arenotentirely removed. Also, after continued use single beater arms are subject to another objection, namely, they twist laterally or glance sidewise when 4vstriking the carcass, thus instead of scrap- 'ing longitudinally of the carcass, a stroke at an angle with the carcass is obtained which not only decreases the efficiency of the beaters but the blades of adjacent beaters clash together mai-ring and cutting the same, which in turn sometimes tears or injures the skin of the carcasses acted upon.

It is an object of this invention to provide a flexible beater in which the beater while resilient, affords somewhat greater' resistance than has heretofore been the case so they may not yield so readily when striking the carcass.

is connected with the end of the beater adf jacent the knives.

It is further an object of the invention to afford a construction in which the beatcrsf each consistof a web of suitable material such as canvas belting on which are secured scraping knives, and' in which the cnds'of the web or webs are connected on opposite sides of' the shaft to afford a bracing effect and to resist the rearward bending of the beaters.

It is finally an object of this invention to provide an exceedingly durable bea-ter capable of withstanding continued and severe usage. without losing its resiliency, which keeps its ,normal shape indefinitely and which retains its stiffness or pressure.

The invention embraces many novel features an'd consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure l is a fragmentary perspective View of a shaft provided with beaters embodying my invention. Fig. 2 .is a view taken in transverse section of the shaft showing Vtwo of the oppositely disposed beaters. Fig. 3 is a face view of the web or belting showing the` scraping knives in place and the belting or web detached from the shaft. Fig. -l is a reduced fragmentary view similar to Fig. Q. Fig. 5 is a fragmentary face view of the san'ie.

As shown in the drawings: A indicates a portion of one of the shafts of a scraping and dehairing machine such as described in my prior applications, onwhich are secured flexible beaters andv 'Scrapers indicated by B--B,4 whichv stand outwardly approximately at right angles from the shaft and are rigidly secured thereto. Each of the beaters in the constructionI shown in Figs. l, 2 and 3 comprises, as shown, a single strip of cotton or other suitable belting or fabric,

vstrips forming the oppositely disposed beater. Plates -or strips b2 of suitable stiff 1.0 yet resilient material are secured outside the rear lapl of the beater and one end of each plate extends outwardly alon each rear lap of each beater, as shown in Figs. l and 2, to reinforce the same and to'assist the resiliency of the belting or other material to prevent bending close to the shaft. An outer curved metallic plate b3 is next secured on the shaft by the 'same bolts and the hooked or conyex Vside thereof directed toward the 20 Vextremity of the reinforcing plate b2 so that should the beater be forced rearwardly' by4 contact With'the carcass, this 'also assists in holding the same from the shaft. Near the :Venter end of each beater are pro vided curved scraping-blades b4, which are conveniently arranged alternatelyv in two or more rows transversely the beater.

In the construction vshown in Figs. l, Q and 3, it is evident as the beater is bent somewhat rearwardly in passing the carcass the bend at the outer end of the beater is changed in form andv may extend beyond .the knives. I therefore for some purposes, prefer to construct the beaters as shown in Figs. 4 and 5, with the knives b4 either on the end of the beater web B3 or upon a short web of tlie beltin'g or fabric B2, with which the webs or belting B3 and B* are rigidly secured by riveting. These are engaged on opposite sides f the shaft 4as before described.

The operation is as follows: In either construction the rotation of the shafts tends to thr'ow the beater centrifugally outward, bringing the knives with more or less violence in contact with the cai-cas` previously .st-aided. so that the knives act to beat, scrape and pull the hair, bristles. scurf, etc., therefrom. The rearward y directed end of the beater web serves to brace and exerts considerable pressure against the front web which greatly assists the beaters in resisting the tendency to spring rearwardly by contact with the carcass and returns the beaters to normal preventing buckling of the same or lshort bending of the outer ends of the heaters. l()bviously, therefore, the rear web may be said to be a somewhat resilient brace for the scraping end of the beater and serves to greatly augment the utility thereof. l

Of course, various details of construction may be varied. I therefore do not purpose limiting this invent-ion Otherwise than necessitated by the prior art.

l claim as my invention:

l.' In a device of the class described a shaft, oppositely disposed beaters secured thereto, each'constructed of a piece of flexi- .ble belting bent to form a loop and having' their'ends secured on opposite sides of the shaft, said .opposed 'beaters having their' ends overlapped, curved scia iing'blades secured at one end to one sid of the beaters and a shortl reinforcing flexible member on the rear side of eachbeater to prevent short bending of the beater.

Q. The combination with a. shaft of a beater comprising a resilient and flexible strip of material. having the width of the stripv directed longitudinally of the shaft and the ends folded against opposite sides of the shaft forming a loop in the beater, a plate curved at 'the outer end, means secur ing the.' ends of. the strip and plate to the shaft. and blades secured to the beater at the loop.'

A beater of the class described cornprising a piece of flexible material forming a loop with theends connected o-n opposite sides of the beater shaft7 and Scrapers rigidlf.Y secured near the outer end of said beater.

at. In a device of the class described'a shaft, a beater comprising a strip of resilient and flexible material having one end on one side of the shaft and the opposite end inthe opposite `side of the shaft providing a loop which lies outwardly from the shaft, means for securing the ends of the beater to the shaft. scraping blades secured to the heaters adjacent the loop and a member se# cured to the shaft to prevent short bending of the beater.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
